- To all whom it may mm Be a known that I, LAwnnnonE; Am-

SON, a citizen of the United States, residing at Modesto, in the countyof Stanislaus and State of California, have invented new and useful Improvements in ,Loose-Leaf-Binder Extensions, of which the-following" is a specification.

This invention relates to loose" leaf ers, and particularly'to binder. extensions for sectional post loose leaf ledger binders. One ofthe objects of the present invento any binder regardless of size, and which renders said ledgers fiat surfaced and. easy to handle.

Another object of the invention 1sto provide a device of this character in whlch the removal or insertion of leaves may be quickly and easily accomplished, and in which slotted'leaves may be entirely eliminated;

Further objects will hereinafter appear. The invention consists of the parts and the construction and combination of parts as hereinafter morefully described and claimed,having reference to the accompanyin ,drawlngs 1n whrch Figure 1 is a perspective viewof a loose leaf ledger showing the application of the invention.

Fig. 2 is an enlarged side elevation partly in section. I

Referring to the drawings-1n detall, A intlicates the base of a loose leaf ledger-to which is hingedly secured, as at 2, a cross bar 3. Secured to the bar is a pair ofleaf supporting posts 4:, and also secured to the bar 3 by means of the posts 4: 1s a pairof extending arms 5. Secured on the outer end of each arm 5 is a pin 6, and slidably mounted on each pin in a vertical direction is a post 7. The pins 6 extend within the post 7 as shown in Fig. .2, and the upper end of each pin is provided with ahead 8. to permit the insertion of coiled springs 9.'

The posts 7 due to the tension of'the springs 9 are normally held in the depressed position shown in Figs. 1 and 2, or in contact with the outer ends of the arms 5. They may, however, be moved vertically upon the pins 6 by exerting an upward pull, as will hereinafter be described.

Formed in the upper end internally thereof is a threaded section 10,

of each post and and adaptedto bescrewed'into said threadedsectlon is an extension post. 11. The up per end of eachextension post 11 is also internally threaded as shownat 12, and it is,

therefore, possible to apply a goosefneckextensionv such as shown at 13 to form a connection' between the posts' l "and 11. "Each' goose neck is provided with a threaded pro ection which adapts each goose neck to be screwed intoitsrespective post '11. The op posite end of each goose neck is, however,

provided with a" plain projection shown' at 14,'wh1ch':1s adapted to berece'iv'ed by a recess 15 formed in the upper end'of each post 4. The posts4 secured'to. the-cross bar areprovided forthe purpose of receiving the leaves16 of the ledger. -Theseleaves are merely perforated as shown at 17 to pass over the posts and practically any number.

desired as extension posts such as at 11 may be added, both to the posts 11 and the posts 4.

The goose necks 13 will at all times form v a connection between the respective posts, and 1tf1s therefore, possible to pass the leaves from one post to the other as shown in Fig. 2 when the ledger is being used, and 1 it can also be seen that a flat surface is provided on either side of the ledger when the.

leaves are turned.

In actual operation if it is desired. to insert or remove leaves it is only necessary to grasp the goose necks 13and pull the same in a vertical direction. The pull thus exerted will cause the extension posts 11, and also posts 7 attached thereto, to move upwardly on the pins 6 against the tension of the springs 9. This upward movement brings the projecting ends 14 of the respective necks out of the pocketsformedin the upper ends of the posts 4. It is then possible to turn the goose necks into the dotted line position shown in Fig.2. As the posts 7are freely turnable about the pins 6, new leaves may, therefore, be readily added or removedwithout resorting to the necessity I ofemploying slotted leaves such as are now commonly employed, and, which might readily become torn or otherwise defaced.

The simplicity of the structure involved permits the device to be attached to any ledger regardless of size, as it is only necessary to fasten the arms 5 in any suitable.

manner to the cross bar 3. The simplicity of construction furthermore renders the device, as a whole, simple to operate, and fur thermore provides a ledger which atwall times presents a flat surface to be Worked upon.

v what I claim While specific means is here shown for attaching the arms 5 and the posts-7, I wish it understood that this construction, toge'ther with the materials and finish of the several parts employed, may be such as the experience and judgmentof the manufac turer may dictate and varying conditions m-a require.

aving' thus described my invention, and desire to secure by Letters Patent is 1. A binder extension for 106% aa ledg;

ers and the like consisting of a base having a, bar hinged along one edge, parallel. arms having one end fixed to the bar and projectingoutwardly therefrom, vertical posts 7 having upwardly extending pins at the.

projecting upward from the bar and lockmg'the bar and arms together, said arms posite ends formed to enter sockets in the bular posts [upperends of the posts'extending up from the bar.

22- In a loose leaf binder extension" of the character described, a, base plate having a bar hinged to one edge, parallel arms extending outwardly from said bar, posts extendingup from said bar and serving to secure the arms and'bar together, pins projecting from the'outer ends of the arms, tu-

held down, extensionsof'said .posts parallel with the first named posts, and arched con nections having one end secured to the said post extensions and the opposite ends-with a socket connection to the bar attached posts, said varches and the tubular posts be ing disengaged and turnable with relation to the socket posts by compression of the f springs and'lifting the extension posts.-

slidably fitting said pins," springs by which the posts areunormally In testimony whereof I'have hereunto set 7 my hand in the presence of two subscribing;

witnesses. Y
